The Mechanism of Nickel Corrosion in ENIG Deposits and How to Mitigate It

ENIG specs call for examination corrosion for a continuous intermetallic formed between the nickel layer and bulk solder. Can solder wetting balance testing predict the acceptability of ENIG deposits with level 2 or 3 corrosion? READ MORE...

Maxwell and Transmission Lines

Many electronic engineers leave Maxwell to the textbooks. But in logic, the rise times for signals are often less than a nanosecond – bandwidth that invites unwanted radiation, interference and crosstalk. Can Maxwell’s equations help? READ MORE...

The deal includes all EDA content and software created by Accelerated Designs, including its database of 7.2 million parts, Ultra Librarian library tool, and personnel.

“One of the many challenges an electrical engineer faces during the design phase is getting accurate and usable symbols and footprints,” said Manny Marcano, president of EMA Design Automation. “Accelerated Designs’ library is the world’s largest library for EDA symbols and footprints, offering over 7.2 million quality parts to choose from. Additionally, Accelerated Designs offers services to enable any IC vendor to quickly and easily create the EDA library content its customers need when choosing their components.

"We also hired all of Accelerated Designs’ existing personnel, both to retain their expertise and so that existing Accelerated Designs’ customers will experience a business-as-usual transition through the change in ownership,” said Marcano.

“Becoming part of EMA allows me and my team to focus on our core expertise: EDA part creation, library tools, and services,” said Frank Frank, president and CEO of Accelerated Designs. “With EMA’s help in marketing and business development, we’ll be able to expand our offerings and provide more value to our customers.”

Digi-Key, which partnered with Accelerated Designs in 2015 to provide symbol and footprint generation in the specific format for nearly any EDA tool, applauded the deal. Randall Restle, Digi-Key vice-president of applications engineering, said, “This allows our customers to quickly and easily design in new parts or even obtain customized libraries from a pool of hundreds of thousands of Digi-Key’s parts, indexed with a Digi-Key part number, and compatible with their EDA tool. Our successful history with both EMA and Accelerated Designs encourages me that the combination will be a positive change for Digi-Key and our customers.”

Marcano said the deal reinforces EMA's commitment to leadership in symbol and footprint generation, which, EMA asserts has been "largely ignored" in favor of toolset features.

“EMA now owns a tremendous wealth of symbol and footprint content, and my goal is to rapidly evolve the Accelerated Designs library to be the ‘gold standard’ for the EDA industry,” said Marcano.
